GEARING.

vented new and useful Improvements in Gearing,.of which the following is a specifieation., 1

'l`his ..inventioii relates to a gearing es-A pecially-adapted for use in disk pulverizers struction.

the. vsaid Bnjcii tiled December 9, 1909, Seria1 .f.No`. 582,267. In machines of this charaj'cter the disksare given 'a planetary motion vin order. tol prevent .grooves forming on them, o neof the objections to such mae is thenoise made by the gearing which uces this planetary movement,

.and one fthe main objects of the presentinveiitioiifis to produce the, required planetary nioienient with as little noise as possible, and yto provide a mechanism for producing the planeta-ry movement whichv is o f comparatively simple and economical con- Anoth r object of the invention is to pro videnovel and improved means for adjust- Fig l "proved nieanstiior lubrication.

the action'of the stationary "disk 4f, so that 'all lines of rotation 'on-,the 'face ofthe disk 5 constantly change position with respect to the face ot the stationary disk 4 which pre. .vents grooving of the disks. The rotating disk 5 i's carried on a shaft 6, the latter being' mounted 1n a hub-7 which is journaled Pasadena, in the county of Los Specification of Letters Patent. Patented l 3 1'. 26, 1912.

in the bearing 3. The h ub 7 is bored eccentrica'lly to receive the shaft 6, 'so that the latter has an eccentric position the hub 7 and bearing 3. Thus as th rotatesthe shaft 6 Will be given eccentric movement. vThe hub 7 is frin as part of a flange 8 which is cuppedi'andE v' carries an internal gear), the teethof' which aretriangular, as .shown in4 Fig. 3, andgithe internal gear 9 is preferably formed of babbitt which renders it.practical1y noiseless in' operation and enables its easy.'

The-liufsliinv ing 14 has a bearing on an eccentric huhf.

disk 19, theiatter being secured toA thex'shaft G by a `feather 2 0' and rotating therewith. At the other end o'the frame-1 isa bearing 21 in which ismoiinted a stationarv hollow.'

T hus .as `t-he pulley: 25 rot-ates,' it imparts 'rotation to; the i driving" disk. 1 9 and.. thef latter through the feather 20.drives theshaft 6, thereby imparting axial-'rotation 'toftl'ie ro;l i tating pulverizing disk 5'. As the'"aliatt 6 thus rotates, obviously the driving disk 19 which is mounted thereon, and engages the feathgeffQOZaccompanies the .shaft v6 iii', its eccentric bodily movement, the stra. 26 permitting of this relative movement o the 11( driving disk 19 with respect to the pulle 25. And as'theshaft 6 anddriving disk 18 which is formed as part, of a drivingigo 19 move eccentrically bodily, the latter carries bushing M bodily whichv in turn imparts an eccentric bodily movement tothe `pinion l0. Without, however, turning the 5 pinion axially,the pinion l() being bolted to the disk. 8, being held against any .axial movement by strap .16 and bracket "17, which connection, While preventing axial rotation, permits the eccentric bodily movement. y As the pinion 1 0 thus moves eccentrically bodily, its-teeth are given a planetar'y movement around the teeth of ythe in-` ternal gear 9 and owing to the less number of teeth in pinion l() than' in internal gear Q, it' results in imparting a very slow axial rotation to the internalV gear 9 and as the internall gear 9 is thus rotatedthe flange 8 to' which it "is, attached rotates the hub 7 and the latter carries theshaft 6 bodily in an orbit eccentric to the axis of rotation of the hub' 7, thus moving the rotating. pnl` veriz'in'g disk 5 in an orbit eccentric to the axis 'of'the stationary pulverizing disk 4. Thef non-revoluble' pinion 1'0, while held from rotation by the ear 15, link 16 and bracket 17, is permitted by the rocking movement movement.

The end of the shaft 6 is provided with44 a socket 27 in which is a hardened steel* button 28 against Whichthe enchof a thrust pin '29"bears, the' outer end of the thrust "in beating .against the fiber washer 30 in ajc'ap '3l screwed on the threaded ontei;l endl 3 5 of the stationary arbor 22, the"cap 81 being rovided with a hand Wheel 32 permitting 1t to beturned, the .tace of the hand wheel 321 having a series of radial vgrooves t which are-detachably engaged by a finger 3ft 40 onfa'sleeve 35, sli'dable on the outer endof theshat '22, 'fa vcoil spring 36 bearing against` the sleeve 3 5 and holdingthe arm 314 in engagementvvith one of the grooves Y W thinthc cap 31 is formed a grease chainh intofwhiclrgrease may be placed and. which `will pass along the hollowarbor 22 "nd"'thi 'ough grooves 38 to .pulleys `24 fWhat weclaim, is: -LA,s haft, a, revoluble hub having an .eccentric bore in which the shaft is joue. n'aledffa, driving disk Aeccentrically seciired .tn thehaftandhaving a bodily eccentric movement therewith, a nonrevolnble pinion journaledon the driving disk and having a bodily eccentric n i'ovement i therewith, an internal, geanfineslringwvith :said-l pinion Sand rotated; by .-tli efbodily, movement of.
